Third Eye On-Lens Micro Bicycle Mirror

I hate writing a bad review, but this was THE WORST purchase I've made online. I have used a mirror attached to glasses for years, racing, cross country, centuries, etc. This seemed to be the next best thing. I couldn't put it anywhere on my glasses, (3 pairs) without it hitting my eyelashes, no view rear view. After and hour of futzing with it I just threw it in the trash. Maybe it works with flat glasses, but anything curved is a no go from my experience. Those that had had good luck, good on you. I couldn't ever recommend this.

It is simple to use. I mounted it on the upper left hand corner of my eye glasses. I actually used a small piece of the adhesive in the packaging to mount it on my glasses and it is staying put! Although the base of it is stationary, The mirror itself is not, which is quite important. The mirror is attached to the base with a swivel which allows me to adjust the angle of the mirror to exactly where I need it. For its small size, it really does give me a very good and complete view of what I need to see so I can be safe when riding my bike. The only other thing I would suggest getting is an eyeglass lanyard as well. This will help to keep your glasses still so the mirror stays at the desired angle.

The mirror itself is great and even has a cute little pivot. I love the idea, and wanted something like this for a while (mainly for walking, so I am forewarned whenever some knucklehead on a Bird scooter is about to blast by within an inch of me at 2000 mph, as seems to happen more and more frequently these days). This device comes close but doesn't quite cut it for 2 reasons: 1. The glue-dots they provide are ineffective. I needed 3 of them just to get the thing to stick to my sunglasses, and even then it was quite loose and clearly would fall off in a matter of miinutes. I understand there's a fine line to walk here in order to secure the thing without damaging the glasses and still allow it to be removed. But their solution doesn't work. My guess is that you'll need to use some sort of stronger bonding agent, but then you won't be able to remove it without damaging the coating on your glasses. If the coating is only on the outside, you should be fine, though. 2. How effective this thing is depends very heavily on your eyeglasses and head shape. If your glasses are no wider than your face, you'll have very limited rear-vision (and it won't be directly behind you). I found that even with the mirror mounted at the farthest point on the glasses, I needed to turn my head about 30-40 degrees to see what was coming up behind me. Better than nothing, but definitely not like a side-view mirror. This isn't their fault, of course. It's simple geometry. But it's important to set your expectations accordingly. If you have wide glasses which protrude from the sides of your face a lot, this mirror will be quite effective. Another possibility I have yet to try is finding a way to mount it on the rim.

Really wanted this to work. On the plus side, I had no issues using the supplied adhesive dots, and had no issues with the mirror pivot (never broke and was easy to use). "Too small" is over simplifying the issue. The mirror (mine, at least) seems to have a small amount of magnification. Looking in it while wearing glasses, with my partner standing about 15 - 20 foot behind me, their face nearly filled the mirror area. I wouldn't be too surprised if that wasn't the intent / this was a flaw, but things were very clear in the mirror. It's just that viewing such a small area makes it really difficult to quickly figure out what big things are going on behind you - which is the whole point of this thing (is a car approaching?). I used it on some fairly wide glasses (Zenni SKU# 232924) and placed the mirror nearest to the edge of the lens. Looking at the mirror is somewhat of a struggle. Looking through the mirror for a few seconds causes eye strain issues. I'm assuming that angle is too extreme for me to use - I would have to move the mirror inward and/or away from my eye to fix that issue. In that position, it certainly isn't able to see directly behind me. It's about a 30 degree angle off directly behind me, so I have to turn my head an awkward amount before it could even see cars coming... at which point, I can just turn a bit more and use my eyes to look back. It's not like I can focus on anything in front of my while trying to aim the mirror backward and peer through that tiny circle. IMO, this *might* work for me if it were a MUCH bigger rectangle that covered the entire edge of my lens. It'd also help if the pivot part wasn't so thick - that moves the lens closer to your face by over 1/8". It is super light weight, doesn't get in the way, has a very clear mirror, stays in place well enough, and is easy enough to adjust. But if you're not worried about looking like a dork, try the Take A Look mirror first.

The first step in setting up this item is to locate the proper point on your glasses and glue it into place. They do not supply the glue or recommend what type of glue to use. Super glue would not hold, so I went to Gorilla glue which appeared to hold. Unfortunately, after gluing the device into place, I was unable to focus on the mirror. Then, when I tried to adjust the angle of the mirror by moving it on its tiny pivot, the mirror separated from the pivot. It is a very flimsy set-up and I basically wasted my money. From reading the other reviews, it appears that others have been able to make this thing work for them. I finally settled on the Bike Peddler Take a Look mirror which is sturdy and is very easy to use.
